77bf144d52 Inline hot parts of bitwise instructions into hybrid VM 2020-01-14 13:47:10 +03:00

9c9a833f9c Actually remove the YIELD key specialization 
I only adjusted the code before, without switching to TMPVAR.

da3b245715 Reduce YIELD_FROM specialization 
Generator delegation is a complex compound operation, it does not
make a lot of sense to optimize refcounting here to this degree.

2aba10be4a Reduce ZEND_THROW specialization 
Throwing is very expensive due to the need of gathering the backtrace,
so it makes little sense to optimize refcounting to this degree.

1eb706179f Avoid references in TMP var 
Make sure we deref the OBJ_IS result, because we store it in a TMP
var, which is not allowed to contain references and will cause
assertion failures in the unspecialized VM.

This also partially reverts fd463a9a60,
which merged the TMP and VAR specializations of COALESCE to work
around this bug.

An alternative would be to change the result type of OBJ_IS back
to VAR.

a50198d0fe Implement ??= operator 
RFC: https://wiki.php.net/rfc/null_coalesce_equal_operator

$a ??= $b is $a ?? ($a = $b), with the difference that $a is only
evaluated once, to the degree that this is possible. In particular
in $a[foo()] ?? $b function foo() is only ever called once.
However, the variable access themselves will be reevaluated.

b0af9ac733 Avoid live range references in opcodes 
Don't store the live range of the freed variable for FREE_ON_RETURN
frees, instead look it up at runtime. As this is an extremely
unlikely codepath (in particular, it requires a loop variable with
a throwing destructor), saving the runtime lookup of the live range
is not worth the extra complexity this adds everywhere else.
